Title: Blast furnace operation using reductants of different reactivity - comprising metallurgical coke and carbonaceous material of lower gasification temp.
Inventor: SCHNEIDER MICHEL
IPC: C21B5/00
Filed: 1980-06-10
Abstract: The blast furnace is charged with an iron-contg. charge and at least two types of solid iron oxide-reducing materials of different reactivity. One material is conventional metallurgical coke and a second material is a carbonaceous material having a gasification temp. less than that of the metallurgical coke and used in amt. at least 1 (pref. 1-10, esp. 2-5)% wrt. the metallurgical coke. The use of a lower gasification temp. reductant beads to a lower temp. (about 850 deg instead of 900-1000 deg.C) in the reserve zone of the furnace, which is more suitable for redn.esp. of hematite agglomerates. This gives a redn. in coke rate of about 20-30 kg/tonne pig iron and an increase in the CO2/(CO+CO2) ratio from 0.25-0.30 to about 0.35 in the reserve zone. The conventional metallurgical coke provides the necessary mechanical properties of the reductant.

Patent FR-2487927-A1 (FR)
Inventor: BLOCH GEORGES
IPC: F16L33/08
Filed: 1980-08-04
Abstract: The invention relates to a hose clip, which is also designated as a hose clamp. The hose clip contains a band (11) and a turnbuckle with covering hood (17) and screw (15) for fastening and fixing the ends of the band. Between its ends (12, 24'), the band (11) is elastic in the longitudinal direction. The elasticity is produced by corrugations (341, 342, 343, etc.) which compensate for diametrical constrictions of a hose which is enclosed by the hose clip. The invention is used, in particular, in the case of mounting a hose on a connection stub.

Title: Master slave distributed clock arrangement - uses master clock emitting time check pulse daily or weekly to slave clocks running independently
Inventor: SEVERI DIDIER
IPC: G04G7/00
Filed: 1980-11-24
Abstract: The system includes a number of individual clocks (1) each of which has a circuit (42) for resetting them to the correct time in response to a received electrical signal. A high precision clock mounted centrally (42) emits daily or weekly pulses in order to correct the time displayed by the other clocks. The signal is emitted via the mains supply network, preferable between the phase and neutral lines of the supply. A ferrite ring (15) has a number of windings formed on it. The master clock provides pulses as input to one of these windings, while another secondary winding is connected via filtering circuits to the mains. The filter prevents the return of mains current, while allowing the transmission of the correcting time pulse. The pulse is detected by 'slave' clocks, and used to correct their displayed time.

Title: Sampling probe for blast furnace - where very long lance can be used to remove sample of solid charge inside large furnace
Inventor: KAJIHARA TOYOTA
IPC: C21B7/24
Filed: 1980-12-19
Abstract: In the blast furnace casing is a hole via which a lance probe can be driven horizontally into and out of the furnace. The hole is aligned with an outer, water cooled tube, which is provided with a valve so gas cannot escape from the furnace. A set of rolls is used to straighten lance when the latter is driven by a trolley towards hole via a gas seal. A rotary saw is pref. located near valve, so a lance which has become bent in the furnace can be cut to simplify its extn. The front end of the lance pref. forms a cavity via which a sample of solid material can be obtd. from the charge in the furnace. For example, when a tubular lance with length 14 m is used for a furnace with internal vol. 5000 cu.m.

Title: Automatic electronic flowmeter - has measuring tube introduced in fluid conduit with ultrasonic transducer of wall for repeated liq. level measurement by echo detection
Inventor: GUILLON JEAN
IPC: G01F25/00
Filed: 1981-01-30
Abstract: The flow-meter includes a measuring tube (4) connected to the pipe (1) in which the flow rate is to be measured. A valve (6) is placed on this pipe (1), and is used to fill or empty the measuring tube (4). To measure the flow rate, the time needed for the surface of the liquid to pass from the low threshold (SB) to the high threshold (SH), or vice versa, is measured. The two thresholds (SB,SH) define a fixed volume. The measurement is made automatically instead of manually and visually, by using an acoustic transducer (7) which is placed on the surface of the measuring tube (4). The transducer (7), associated with a transceiver (24), is used to measure the level of liquid in the measuring tube (4), and an electronic stop-watch measures the time. The calculator is provided for information processing.

Title: Auxiliary energy controller for trolley bus crossing intersection - has inertia wheel accumulating energy while vehicle supplied from overhead lines and sustaining motion under beacon control
Inventor: QUEVEAU GERARD
IPC: B60L50/30
Filed: 1981-03-24
Abstract: The system uses stored energy to carry the vehicle over the intersection without an overhead cable supply. The system consists of a position signal beacon (17) at the boundary of the overhead cable section, a position detector (18) mounted on the vehicle and responding to the signal beacon, and an inertia wheel energy storage (10) which accumulates energy from the overhead lines while the vehicle is in an overhead line section. A controller (20) switches the supply to the drive motors (14) between the overhead lines (1,2) and the stored energy source. Alternatively, the energy required during crossing the junction can be stored in accumulator batteries.

Title: Wet granular material drainage feed - has base which forces hot gas through unsaturated portion of material pile
Inventor: BERTHOD LOUIS
IPC: F26B7/00
Filed: 1981-07-28
Abstract: The drainage feed is for wet granular phosphate after mining and washing. The material is piled so that the water can percolate downwards, that appearing at the base being extracted to prevent its level rising. The drained material is extracted from an intermediate portion of the pile high enough to prevent capillary action causing the free water to rise to this level. Hot gas is also forced through the unsaturated portions of the pile, to heat the material and aid percolation of the water by reducing its viscosity and surface tension.

Title: Automatic key reproducing grinder - uses pivotable milling head sensor to present groove or edge cutters to blank
Inventor: ALPHONSE JEAN
IPC: B23C3/35
Filed: 1981-09-18
Abstract: The automatic grinder reproduces a grooved key, using a horizontal slide (3) to mount the model (9) and the blank (8) keys secured in parallel vertical planes by two sets of jaws (a,b). A milling cutter (45) with a sensor (46) locates opposite the keys and its distance from the keys is varied in a reciprocating cyclic manner permitting slide displacements. The cutter is fixed in position but can pivot about horizontal axis to present either a groove-cutting (45) or an edge-cutting (61) tool to the blank. In addn. to forward movements in a horizontal plane the slide is also imparted with cyclic displacements in an offset circular trajectory in a vertical plane normal to the cutter. The speed of the latter displacements is stepped up between cuts.
